Hi there and welcome
Do you mean it is asking you for the original google account the phone was set up with?
Ok, you must enter this in if you ever wish to use the phone again. It's a security implementation Google has done and nothing, even Google cannot get around this.
Did you initially set up this phone?
If you click on my link below, can you sign into your account there?
Whats the exact message you get on the phone?
